LinuxCNC 2.9.9 WITHDRAWN

Fri, 03 Jul 2026 17:22:00 -0600

LinuxCNC 2.9.9 has been WITHDRAWN

Please do not update to 2.9.9 if you use probing routines. A fix to a long-standing bug has broken many probing routnes that were working around the bug. Context here https://forum.linuxcnc.org/38-general-linuxcnc-questions/58927-g38-2-weird-behaviour

2.9.10 fixes this and can be downloaded from github: https://github.com/LinuxCNC/linuxcnc/releases/tag/v2.9.10

Unfortunately I am having a problem with the archive signing key for Trixie onwards and so haven’t been able to release to the repositories yet.

Please bear with me while I attempt to sort this out.

Andy Pugh, Incompetent Release Manager.

LinuxCNC 2.9.9 released

Sun, 28 Jun 2026 09:02:00 -0600

LinuxCNC 2.9.9 has been released.

This is a bugfix, feature improvement and security enhancement release.

To address the last part first, it has been noted by two separate people that a weakness in the RTAPI allows for privilege escalation as it runs as setuid root (to give direct access to hardware). Given the use-case for most LinuxCNC machines this is unlilely to be a problem in most cases; most hobby users will have root access anyway. The issue has been patched in both 2.9 and in the development branch.

Free Software fabrication gathering in Norway 2026

Tue, 31 Mar 2026 05:00:00 -0600

You are invited to a small LinuxCNC and free software fabrication workshop/gathering in Norway this summer, over the weekend starting June 26th, 2026. As last year, the gathering maintain a slightly broader scope and welcome people outside the LinuxCNC community. It is organised as an unconference, where participants create the program upon arrival.

The location is a metal workshop 15 minutes’ drive from Gardermoen airport (OSL), with plenty of space and a hotel just 5 minutes away by car. We plan to fire up the barbecue in the evenings. Please let us know if you would like to join. We track the list of participants on a simple pad for food capacity planning. Please add yourself to the pad if you are interested in showing up, and join the Signal group.

LinuxCNC 2.9.8 released

Sat, 03 Jan 2026 08:42:00 -0700

LinuxCNC 2.9.8 has been released.

This is a minor update release, mainly of interest to those using the hal_gpio HAL driver (mainly Pi users)

Changelog:

backport #3516 to fix #3679
Only initialize python if not yet initialized.
hal_gpio: Adapt to use libgpiod3 or libgpiod2 according to what is installed
Merge pull request #3671 from smoe/docs_image_handling
core-components.adoc remove duplicate descriptions
Merge pull request #3642 from LinuxCNC/2.9_#2460
Update LinuxCNC RTAI Install instructions
Merge pull request #3555 from smoe/lintian_warnings
Merge pull request #3588 from f355/2.9
[ci] publish releases with artifacts
debian: Addressed lintian warnings
axis.py: restore mdi queuing provision #2460

The main driver for the release was the change in API for the gpiod driver. This resulted in the hal_gpio driver not being built under Trixie.

As of this release the default Debian version for the ISO for both PC and Pi has been updated to Trixie. The LinuxCNC repositories have been updated for Buster, Bullseye, Bookworm, Trixie and Sid.

Note that released debs are also now available on the LinuxCNC GitHub under “Releases”: www.github.com/https://github.com/LinuxCNC/linuxcnc

As always, thanks to all the developers who make this possible, and for this release especially:

Bertho Stultiens Dewey Garrett Konstantin Tcepliaev Robert Schöftner Steffen Möller

LinuxCNC 2.9.7 released

Sun, 26 Oct 2025 17:11:00 -0600

LinuxCNC 2.9.7 has been released.

This is another bug-fix release to fix an unexpected interaction in a previous bugfix. (In this case the driver for the popular XHC pendants was incompatible with changes made to HALUI pin creation)

In addition changes to the CI (continuous integration) in Github mean that the install debs will be available from the LinuxCNC Github repository under the “releases tab”

This update is for all users, but especially users of the XHC pendants and Gmoccapy.

Packages for 2.9-uspace for amd64 (PC) and arm64 (Pi) for Debian Buster, Bullseye, Bookworm, Trixie and Sid have been added to the linuxcnc repository. If you installed from one of our live images or Pi SD-card images then the update should be available immediately.

If you installed into a normally-installed Debian from the Debian repositories then hopefully the new version can be queued up for the next point release. If you can’t wait then it is possible to add the LinuxCNC repositories to the apt sources. One way to do this and install the security keys is via the shell script here: https://linuxcnc.org/docs/stable/html/getting-started/getting-linuxcnc.html#_installing_on_debian_bookworm_with_preempt_rt_kernel

This script has been updated to include a new, longer key required by Debian versions from Trixie onwards.

At the moment the live-image installer and SD card images will install 2.9.4 but update should be trivial (and possibly automatic)

RTAI is still supported, but in the short term building from source is likely to be the most expedient way to get 2.9.7 on that platform.

Changelog

[ci] publish releases with artifacts - GitHub now builds release debs
Revert 7d9ee66 to address #3583 - halui functions stop working in 2.9.5/6
Merge pull request #3512 from Sigma1912/patch-1
Gmoccapy: Fix arrow key up/down bug in tooleditor

As always, we couldn’t do this without the contributions from the community, so many thanks to:

LinuxCNC Meetup in Stuttgart

Sat, 27 Sep 2025 17:50:00 -0600

There will be a meeting of LinuxCNC developers, users, and enthusiasts in Stuttgart, Germany, during the weekend from Friday October 31th to Sunday November 2th 2025.

This will be a pretty informal meeting, there is no registration, no entrance fee, no badges, no speakers, and no set agenda. It is a chance for people interested in LinuxCNC to meet each other, show off their projects, and talk about issues, fears, hopes, and dreams.

Details and signup here: https://nuudel.digitalcourage.de/dGtDlt4Tzw9tZ3Hn

LinuxCNC 2.9.6 released

Thu, 25 Sep 2025 18:11:00 -0600

LinuxCNC 2.9.6 has been released.

This is a bug-fix release. Shortly after the release of 2.9.5 it was noticed that a fix for a graphics bug in Gmoccapy had resulted in the Axis touch-off dialog box no-longer working for non-zero entries.

This update is for all users, but especially users of the Axis GUI.

Packages for 2.9-uspace for amd64 (PC) for Debian Buster, Bullseye, Bookworm and Trixie and for arm64 (Raspberry Pi 4/5) for Buster and Bookworm have been added to the linuxcnc repository. If you installed from one of our live images or Pi SD-card images then the update should be available immediately.

At the moment the live-image installer and SD card images will install 2.9.4 but update should be trivial (and possibly automatic)

RTAI is still supported, but in the short term building from source is likely to be the most expedient way to get 2.9.6 on that platform.

Changelog

qtvcp -Qt5_graphics: issue 2753; preview wrongly uses INI startup code

LinuxCNC 2.9.5 released

Sun, 07 Sep 2025 16:59:00 -0600

LinuxCNC 2.9.5 has been released.

This is mainly a bugfix release, but includes a new modbus driver for the Mesa UART (update/replacement for mesa_modbus with more flexibility and configurability)

At the moment the live-image installer and SD card images will install 2.9.4 but update should be trivial (and possibly automatic)

RTAI is still supported, but in the short term building from source is likely to be the most expedient way to get 2.9.5 on that platform.

Highlights:

Backport new hm2_modbus driver to 2.9 branch.
Fix probe contact bounce triggering error during decel phase

Report: LinuxCNC Meetup near Oslo

Sat, 12 Jul 2025 16:33:00 -0600

We just completed a LinuxCNC-intense weekend, kindly hosted by Petter in his shop near the Oslo airport and also kindly sponsored by NUUG Foundation and Redpill-Linpro. Petter’s shop is quite a mechanic’s resort.

(If you are upset to have missed it, then it is very likely that the event will be repeated next year at around the same time)

One of the more tangible outcomes of our gathering is a decision to pimp our LinuxCNC gear - Dominic and Asle drafted an idea for LinuxCNC T-shirt. Please have a look at https://sprd.co/tdhbvfn (attention, not write-protected!) and send in your ideas to improve on it or links to alternative shirt designs. Impressive for all attendees was how Andy, René and Petter addressed the LinuxCNCification of Petter’s retrofitted mill. Andy pulled an impressive collection of Mesa cards (for which he created many of the drivers) from his magic bag and in the end it was a custom firmware kindly provided by Mr. Mesa himself that optimized Petter’s setup using three smart-serial Rx channels as differntial encoder inputs.

One of the many side-projects over the weekend was the investigation how a LinuxCNC Live-USB stick could possibly be produced with the Live-Helper https://live-team.pages.debian.net/live-manual/html/live-manual.en.html tools of Debian. The real-time kernel is indeed provided, which was thought to be the largest hurdle. There is some hope that the Debian community could offer such an image directly. But the question is - which packages should be shipping with it? FreeCAD, basic UNIX bits, text editors, web browser, maybe all that is collected in https://blends.debian.org/3dprinter/tasks/cad, https://blends.debian.org/3dprinter/tasks/gcode, https://wiki.debian.org/DebianScience/Engineering, KiCad, … we would like to start a discussion on this topic. The benefit for LinuxCNC to be shipping with a wider selection of tools is an increased awareness by other communities, and vice versa.

The documentation literally did not let us sleep too much. Weblate has a new champion, i.e. Tamil. The only concern is that the translations translate bits that should not be translated. Those bits likely should not be in weblate in the first place, but they are, and not straight-forward to exclude. It is mostly the troff text style instructions that are blocking po4a when syntactically challenging. We have some first scripts to detect such issues and set the .po entry to “fuzzy”. But this will take some more iterations.

Discussion points at the meeting

Suggestions on how to improve the community experience

Revive our Video conferences (René, Steffen, Petter) - Steffen starts an invite, followed by René, Andy, Petter and Dominic Migrating to BigBlueButton on https://www.senfcall.de/.
- Close gaps in communication between LinuxCNC forums and developers
- Discuss upcoming development milestones
- Integrating (or not) regular SmoothStepper
- Custom firmware for SmoothStepper
LinuxCNC-gear (Steffen, René, Dominic Idea to find a site shipping directly that has a good quality
- T-Shirts (Link to a possible T-Shirt design: https://sprd.co/tdhbvfn // please comment - is this good in your opinion? - Dominic)
- Stickers
Debian LiveCD with real-time kernel and LinuxCNC (plus usable CAD/CAM) - any volunteers?
Reference to local user groups
- Hackspace in Hamburg (D) with Dominic
Translations - update with newer version of po4a (Petter, Steffen)
- Fixed newline-error for false-positive itemizations

How to improve our developers’ experience

Documentation
- Folks do not like to have a large repository with too many languages, especially so as only fragments tend to be translated
- Unclear when and how the documentation on the web pages is updated
BuildBot2 to substitute BuildBot - The main buildbot can probably be retired, it is now only building for out-of-support OS variants.
Have all HAL-pins implemented as 64bit (Andy)
- Reduces complexity
- No effect on real time computing
- It is the HAL pins, not the internal compute of whatever complex data schemes LinuxCNC may be confronted with
- Perfect compatibility with all existing HAL files (unlike the current situation in Master with both 32 and 64-bit pins treated separately)
Use Pybind11 to auto-derive Python wrappers of C++ code - Rene
- https://github.com/pybind/pybind11
- Reduces some 2000+ lines of wrapper code to 85 lines

Features that LinuxCNC is missing (or not?)

Not: Embedded template library for real-time parts (Steffen) No dynamic memory is used in our real-time code

We had tons of joint discussions that not necessarily contributed to operational consequences but were always educational and something rubs off on whoever stands by or spans yet another discourse with a follow-up question. In our perpetual quest to identify and augment LinuxCNC’s unique selling points, Andy pointed out that the motivation by NIST to come up with the LinuxCNC precursor EMC as to move from electronic black boxes that shipped with the machine to software and general computers. And they wanted a reference implementation for the G-code someone injected. While there was no alternative at the time, we now have many smaller microcontrollers that could interpret G-code. René then kindly reminded us that Jogging a mill would be not possible e.g. with GRBL because of … and not trivial to add. And yes, for anything small that shall be moving in some well-defined manner, LinuxCNC is not required. But it gives flexibillity. The RPi is possibly important to help with any such transition. Mach 4 is seen, but not Open Source. LinuxCNC brings access to any level of detail of a machine as so desired, also during its run time - because it is Open Source and because of HAL.. Andy stressed that he wanted LinuxCNC to be more useful for those for whom LinuxCNC is already the best tool to use.

Another ongoing discussion is on Andy’s intent to have HAL pins always as 64 bit, also if representing only a single bit to simplify everything. No internal data structure is affected. And it should not affect anything or anyone. Should. In an Open Source world it is just difficult to know what exactly is done in the field. This may be ameliorated by the idea is to improve the links between users (and devs with them) a bit more be restarting the Video meetings we once had not too long ago. Steffen volunteered to host the first, everyone strongly objecting the idea to have a single-individual hosting it, so we pass it around again.

René updated his patch introducing Pybind11 to semi-autmatically create Python interfaces for our C++ code. That reduces some 2000+ lines of code. Hm. The key drawback is that pins that never change, i.e. “parameters”, would need to go.

In the context of Petter getting a new VHDL-implemented firmware for the Xilinx chip on the Mesa card, René and Steffen revisited the Yosys website and found that it now supports Spartan 6 https://yosyshq.readthedocs.io/projects/yosys/en/0.46/cmd/synth_xilinx.html. And there is a plugin for GHDL https://ghdl.free.fr/ for it. Seems like we are not too far away from producing the Mesa firmware with Open Source tools? Would anyone be up to investigate how far we can get already?
